The connectors with the loop on them are cruise and electric lock, i attached a diagram i made for my controller to help me when im wiring it upJohne-bike wrote: ↑Feb 08, 2018 5:58 amI have 2 bikes with 2017 model KT controllers. 1 is a 45amp sinewave and the other a 25amp Square wave, but neither came with a female socket with a male jumper plug inserted. On my installation, I had to cut into one of the 5 wires to my KT LCD6 display, to fit an ignition switch.
On your set up, if it's a red wire, I would think it is ready to connect to an on/off "Ignition" switch. If you disconnect the plug, and you have no power to the throttle and response from the motor, that will be your answer.
Thanks i got mine from conhismotor on ebay, i have to think their wiring loom is pretty good after reading thatJohne-bike wrote: ↑Feb 11, 2018 3:18 amIt's amazing to see how much variation there is in KT controllers wiring harnesses. It must be the way the vendor specifies them when they order from KT Kunteng.
My 45amp sinewave was ordered as part of a complete kit with KT-D12L PAS sensor, KT LCD6 display and Mxus 3000w Hubmotor. My controller has no separate wiring provision for electric lock or ignition.. I had to cut into one of the 5 Lcd wires to connect up an ignition switch. And the cruise control is enabled from the LCD6 3 button controller, with no wiring harness to enable or disable it with a jumper plug.
In addition, niether of my KT controllers came with a wiring harness for powering lights, despite the KT displays on both bikes having the ability to turn on lights along with the display illumination!
The 25amp KT Square wave controller on my Daughter's Fatbike was from a different supplier, but configured exactly the same!
Your KT Controller wiring gives you much more configurable options.
